'Be silent!' hissed Taurus, and he moved out from the wall, cautiously as if treading on razors, lifting the slender tube. Low rumblings rose from the shadows and the blazing eyes moved forward. Conan could sense the great slavering jaws, the tufted tails lashing tawny sides. The air grew tense—the Cimmerian gripped his sword, expecting the charge and the irresistible hurtling of giant bodies. Then Taurus brought the mouth of the tube to his lips and blew powerfully. A long jet of yellowish powder shot from the other end of the tube and billowed out instantly in a thick green-yellow cloud that settled over the shrubbery, blotting out the glaring eyes.
Taurus ran back hastily to the wall. Conan glared without understanding. The thick cloud hid the shrubbery, and from it no sound came.
'What is that mist?' the Cimmerian asked uneasily.
'Death!' hissed the Nemedian. 'If a wind springs up and blows it back upon us, we must flee over the wall. But no, the wind is still, and now it is dissipating. Wait until it vanishes entirely. To breathe it is death.'
Presently only yellowish shreds hung ghostily in the air; then they were gone, and Taurus motioned his companion forward. They stole toward the bushes, and Conan gasped. Stretched out in the shadows lay five great tawny shapes, the fire of their grim eyes dimmed for ever. A sweetish cloying scent lingered in the atmosphere.
'They died without a sound!' muttered the Cimmerian. 'Taurus, what was that powder?'
'It was made from the black lotus, whose blossoms wave in the lost jungles of Khitai, where only the yellow-skulled priests of Yun dwell. Those blossoms strike dead any who smell of them.'
Conan knelt beside the great forms, assuring himself that they were indeed beyond power of harm. He shook his head; the magic of the exotic lands was mysterious and terrible to the barbarians of the north.
'Why can you not slay the soldiers in the tower in the same way?' he asked.
'Because that was all the powder I possessed. The obtaining of it was a feat which in itself was enough to make me famous among the thieves of the world. I stole it out of a caravan bound for Stygia, and I lifted it, in its cloth-of-gold bag, out of the coils of the great serpent which guarded it, without awaking him. But come, in Bel's name! Are we to waste the night in discussion?'
They glided through the shrubbery to the gleaming foot of the tower, and there, with a motion enjoining silence, Taurus unwound his knotted cord, on one end of which was a strong steel hook. Conan saw his plan, and asked no questions as the Nemedian gripped the line a short distance below the hook, and began to swing it about his head. Conan laid his ear to the smooth wall and listened, but could hear nothing. Evidendy the soldiers within did not suspect the presence of intruders, who had made no more sound than the night wind blowing through the trees. But a strange nervousness was on the barbarian; perhaps it was the lion-smell which was over everything.
Taurus threw the line with a smooth, ripping motion of his mighty arm. The hook curved upward and inward in a peculiar manner, hard to describe, and vanished over the jeweled rim. It apparently caught firmly, for cautious jerking and then hard pulling did not result in any slipping or giving.
'Luck the first cast,' murmured Taurus. 'I—'
It was Conan's savage instinct which made him wheel suddenly; for the death that was upon them made no sound. A fleeting glimpse showed the Cimmerian the giant tawny shape, rearing upright against the stars, towering over him for the death-stroke. No civilized man could have moved half so quickly as the barbarian moved. His sword flashed frostily in the starlight with every ounce of desperate nerve and thew behind it, and man and beast went down together.
Cursing incoherently beneath his breath, Taurus bent above the mass, and saw his companion's limbs move as he strove to drag himself from under the great weight that lay limply upon him. A glance showed the startled Nemedian that the lion was dead, its slanting skull split in half. He laid hold of the carcass, and by his aid, Conan thrust it aside and clambered up, still gripping his dripping sword.
'Are you hurt, man?' gasped Taurus, still bewildered by the stunning swiftness of that touch-and-go episode.
'No, by Crom!' answered the barbarian. 'But that was as close a call as I've had in a life noways tame. Why did not the cursed beast roar as he charged?'
'All things are strange in this garden,' said Taurus. 'The lions strike silently—and so do other deaths. But come—little sound was made in that slaying, but the soldiers might have heard, if they are not asleep or drunk. That beast was in some other part of the garden and escaped the death of the flowers, but surely there are no more. We must climb this cord—little need to ask a Cimmerian if he can.'
'If it will bear my weight,' grunted Conan, cleansing his sword on the grass.
'It will bear thrice my own,' answered Taurus. 'It was woven from the tresses of dead women, which I took from their tombs at midnight, and steeped in the deadly wine of the upas tree, to give it strength. I will go first—then follow me closely.'
The Nemedian gripped the rope and, crooking a knee about it, began the ascent; he went up like a cat, belying the apparent clumsiness of his bulk. The Cimmerian followed. The cord swayed and turned on itself, but the climbers were not hindered; both had made more difficult climbs before. The jeweled rim glittered high above them, jutting out from the perpendicular—a fact which added greatly to the ease of the ascent.
Up and up they went, silently, the lights of the city spreading out further and further to their sight as they climbed, the stars above them more and more dimmed by the glitter of the jewels along the rim. Now Taurus reached up a hand and gripped the rim itself, pulling himself up and over. Conan paused a moment on the very edge, fascinated by the great frosty jewels whose gleams dazzled his eyes— diamonds, rubies, emeralds, sapphires, turquoises, moonstones, set thick as stars in the shimmering silver. At a distance their different gleams had seemed to merge into a pulsing white glare; but now, at close range, they shimmered with a million rainbow tints and lights, hypnotizing him with their scintillations.
'There is a fabulous fortune here, Taurus,' he whispered; but the Nemedian answered impatiently. 'Come on! If we secure the Heart, these and all other things shall be ours.'
Conan climbed over the sparkling rim. The level of the tower's top was some feet below the gemmed ledge. It was flat, composed of some dark blue substance, set with gold that caught the starlight, so that the whole looked like a wide sapphire flecked with shining gold-dust. Across from the point where they had entered there seemed to be a sort of chamber, built upon the roof. It was of the same silvery material as the walls of the tower, adorned with designs worked in smaller gems; its single door was of gold, its surface cut in scales, and crusted with jewels that gleamed like ice.
Conan cast a glance at the pulsing ocean of lights which spread far below them, then glanced at Taurus. The Nemedian was drawing up his cord and coiling it. He showed Conan where the hook had caught—a fraction of an inch of the point had sunk under a great blazing jewel on the inner side of the rim.
'Luck was with us again,' he muttered. 'One would think that our combined weight would have torn that stone out. Follow me; the real risks of the venture begin now. We are in the serpent's lair, and we know not where he lies hidden.'
Like stalking tigers they crept across the darkly gleaming floor and halted outside the sparkling door. With a deft and cautious hand Taurus tried it. It gave without resistance, and the companions looked in, tensed for anything. Over the Nemedian's shoulder Conan had a glimpse of a glittering chamber, the walls, ceiling and floor of which were crusted with great white jewels which lighted it brightly, and which seemed its only illumination. It seemed empty of life.
'Before we cut off our last retreat,' hissed Taurus, 'go you to the rim and look over on all sides; if you see any soldiers moving in the gardens, or anything suspicious, return and tell me. I will await you within this chamber.'
Conan saw scant reason in this, and a faint suspicion of his companion touched his wary soul, but he did as Taurus requested. As he turned away, the Nemedian slipt inside the door and drew it shut behind him. Conan crept about the rim of the tower, returning to his
